Corrugated aluminum duct
Corrugated aluminum duct
I need to replace the flex exhaust duct on my Espar heater. This is the 2-1/4" corrugated aluminum flex duct that connects the heater exhaust to the metal exhaust pipe. Seems to be impossible to find. Even SAV is no stock. Anybody have a source?
Any help appreciated...

Try http://www.mcmaster.com and search for aluminum duct hose.
I'm not familiar with the Espar heater but maybe this will work http://www.mcmaster.com/#55015K26 ?

Re: Corrugated aluminum duct
I fitted a Webasto (rather than an Eberspacher) to the 712.....Webasto Australia had the pipe readily available and could supply on demand.
I assume Eberspacher USA (or Webasto USA) would be the same.

Re: Corrugated aluminum duct
You might try a muffler business...
I'm using a mil surplus heater and let my muffler shop run Flex Pipe from the heater exhaust to a rigid pipe that comes out under the tool box.
Those muffler guys have many sizes of flex pipe, check with your muffler guy.

this is what i did. be careful with your measurements or plan on buying more when your first order doesnt fit.
I also used metal duct tape to further close off the exhaust hole.

Re: Corrugated aluminum duct
Tried the muffler shop angle and that turned out to be a bust.
Ordered the above mentioned duct today from McMaster. Should be here soon. Will let you all know how it fits.
Thanks!

Re: Corrugated aluminum duct
The McMaster duct is just slightly bigger in o.d. than ideal. Also it is too rigid to secure with a standard hose clamp. That all being said, it looks like it will do the job.

Re: Corrugated aluminum duct
You need to use a muffler clamp on it.

Re: Corrugated aluminum duct
If you cut the duct and fold it back in on itself then clamp it works just fine.

Re: Corrugated aluminum duct
This duct is waaay too thick and stiff to do that. Good idea though! If it was a little more pliable, I might give it a try. The duct that I got is so rigid that it pretty much stays in place even without being clamped. In any case, it 1000% better than it was before.
